GRAIN-DOOR FOR RAILWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 760,369, dated May 17',1904.

Application filed February 11,1904. Serial No. 193,170. (No model.)

To all whom, t may concern:

Be it known that I, DAVID BENSON ARNOLD, a citizen of the United States,residing' at Terre Haute, in the county of Vigo and State of Indiana,have invented certain new and useful Improvements in Grain-Doors forRailway- Cars; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the io art to which it appertains to make and use the same.

This invention relates to new and useful irnprovements in grain-doorsfor railway-cars; and it consists in certain novel features of conr 5struction, combination, and arrangement of parts, hereinafter fullydescribed and claimed.

The object of my present invention is to improve and simplify theconstruction and operation of devices of this character, and there- 2oby render them more eflicient and durable in use and less expensive tomanufacture.

In the accompanying drawings, Figure 1 is a side elevation of a portionof a railway-car, show'ing its ordinary door in an open position 2 5 andmy improved grain-door partially closing the door-opening. Fig. 2 is avertical transverse sectional view through the car, the grain-doors ineach of its sides being in their closed or lowered positions. Fig. 3isasiini- 3o lar view with the grain-doors in their opened or raisedposition. Fig. 4 is a perspective view of one of the grain-doors. Fig. 5is a similar view of'a grain-door constructed of wood.

3 5 Referring to the drawings by numeral, 1 denotesa railway-car of anywell-known or preferred construction provided in its sides 2 with theusual doorways or openings 3, which are adapted to be closed upon theoutside by the ordinary doors 4C and upon the inside by my improvedsliding grain-doors 5. Said grain-doors 5, as shown in Figs. 1 to 4,inclusive, are constructed of a single piece of sheet metal having itstop and bottom edges bent at right angles to form longitudinalstrengthening-flanges 6 and having at each of its corners integralportions which project horizontally beyond its side edges and are bentto ferm cylindrical pins or studs 7. Upon the inner side of each ofthese sheet- 5o metal doors at about its center is a longitudinalstrengthening-brace 8, of angle-iron, and in the center of the lowerportion of each of said doors is an opening-9, which is adapted to beclosed by an outwardly-swinging relief- 5 5 door 10, hinged at its loweredge, as at l1, and adapted to be fastened in its closed position by apin or keeper 12, which is inserted in a perforated lug or staple 13,projecting from the front of the door 5 and through an opening or slot14:, 60 formed in the door 10, as shown. The graindoors 5 are alsoprovided upon their outer sides with handles 15 to facilitate raisingand lowering the same. The grain-doors slide upon tracks 16 and 17,secured to the inner faces 65 of the side walls 2 at each side of theopenings er doorways 3 and to the rafters 18 of the top or roof 19 ofthe car. The said tracks 16, which are iiat metal strips, extendcontinuouslyup one side of one of the doorways, then horizontally acrossthe top of the car, and then vertically down the corresponding side ofthe opposite doorway. The vertical portions 20 of said tracks 16 aresecured to the inside walls and are spaced from the door-jambs Q1 of the75 doorways to form guideways 22, in which the pins or studs 7 of thedoors 5 project and slide, and the portions 23 of the tracks 16 whichare disposed between the vertical portions 20 and the horizontalportions 24 are curved, as 8O shown, to permit the pins or studs 7toslide freely from one portion to the other when the doors are moved fromtheir lowered vertical position (shown in Fig. 2) to their elevatedhorizontal position, (shown in Fig. 3,) or vice versa. The said tracks17, which are strips of angleiron, are secured on the rafters 18 in aninclined position above one end of the horizontal portion 24 of thetracks .16 and form a continuation of the vertical and curved portionsof the tracks 16 for one of the doors. By providing these tracks 17 thedoor on the side adjacent to which they are located will when in itselevated position rest upon the same, while the other door when elevatedwill rest upon the horizontal portion 24 of the tracks 16, as shown inFig. 3. This arrangement of the tracks for the doors permits of the useof doors of any height, since they may overlap each other to any extentwhen both are in their elevated positions. The tracks 17 have the outeror lower ends resting upon the horizontal portions 24 at their junctionwith the curved portions 23 of the tracks 16, and their inner and upperends are bent to form stops 25, which prevent the uppermost pins orstuds 7 on its coacting door from slipping off of the track.

In order to hold the graindoors 5 in their elevated positions, the pinsor studs 7 on the lower end of the doors are engaged with brackets 26,secured to the door-jambs 21 at points opposite the curved portions 23of the tracks 16. These brackets 26 consist of strips of metal bentadjacent to their centers to form hooks 27 and having their lowerportion 28 curved to act as deectors and guides for the pins or studs 7.It will be seen that when the saidpins or studs move up the guideways 22they will strike said curved portions 28 of the brackets 26 and bedirected inwardly around the curved portions 23 oi' the tracks 16. Thehooked portions 27 of said brackets are so disposed that tbe doors afterbeing elevated and supported upon the horizontal portions 24 of thetracks 16 or upon the tracks 17 may be eas ily shifted to throw thelowermost pins or studs 7 into the said hooks 27, while at the same timethey will be securely held therein against casual displacement.

Instead of constructing the grain-doors 5 oi' sheet metal, as previouslydescribed, I may make them of wood, as shown in Fig. 5. In such casesthe wooden door 30 is suitably strengthened by braces 31 and is providedalong its top and bottom edges with angleiron strips 32, the ends ofwhich project beyond the side edges oi' the door and are bent to formcylindrical pins or studs 33, which correspond to the similar pins orstuds 7 on the sheet-metal doors. In all other respects the constructionof the door 30 is identical with that of the doors 5 previouslydescribed.

From the vforegoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood withoutrequiring a more extended explanation.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the principle orsacriiicing any oi' the advantages of this invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a grain-door for cars, the combination with the side walls formedwith doorways at y opposite points, olitracks extending yhorizontallyacross the top of said car and vertically down the sides of each of saiddoorways, inclined tracks above the horizontal portions of theHrst-mentioned tracks forming a continuation of the vertical portions ofthe first-mentioned' tracks on one side of the car, and sliding doorscoacting with said tracks, one of said doors when elevated being adaptedto rest upon the horizontal portions of the firstmentioned tracks andthe other of said doors when elevated, being adapted to rest upon saidinclined tracks,substantially as described.

2. A grain-door for cars having its upper and lower ends turned at anangle to the face of the door and provided at the ends coincident withthe corners of the door with integral projections forming pins toproject into and slide in guideways for the door, substantially asdescribed. y

In testimony whereoi` I have hereunto set my hand inpresence4 of twosubscribing witnesses.
